    摘要： A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defined an enclosed curved seed pathway extending between opposite ends of the tube. To promote control over the seeds passing through the tube, the tube has a smooth but decreasing cross-sectional configuration between the ingress and egress ends of the tube. The tube generally includes a front wall, a rear wall and a pair of side walls. The front wall is generally separated into an upper and lower portion. An opening in the front wall, which is provided to receive a monitoring device, is associated with the lower front wall portion. In addition, the lower front wall portion is stepped forward relative to the upper front wall portion. The enclosed seed pathway further includes a narrowed front edge extending in an upward direction from the egress end of the tube along some section of the front wall. The narrowed front edge enhances control over the seeds such that individual seeds passing through the tube and deposited to the ground have equidistant spacings between the seeds on the ground. The stepped forward arrangement for the lower front wall portion also allows a monitoring device to be used without disrupting the flow of seeds in the seed tube.

    摘要： A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defines an enclosed curvilinear seed passageway extending between opposite ends of the tube. To promote control over the seeds gravitationally passing through the tube, the seed passageway has a smooth but decreasing cross-sectional configuration between ingress and egress ends of the passageway. The interior surface of the passageway and preferably the tube itself is formed from a material having a coefficient of surface friction ranging between about 0.02 and about 0.10. The enclosed seed passageway furthermore includes a narrowed front edge extending upwardly from a lower end of, the tube and for a majority of the length of the passageway. The narrowed front edge passes beneath and across, in a fore-and-aft direction, the entire ingress end of the passageway for enhancing control over and such that the individual seeds passing through the passageway have substantially equivalent time therein thus promoting equidistant spacings between seed plantings.
